1. Brief Description

The Flare Foundation will implement code changes in the State Connector attestation provider code base that:

• Strengthen the security and stability of the State Connector protocol
• Simplify the on-chain and off-chain interactions with the State Connector by using request and response encodings that align with the Solidity Contract ABI Specification
• Simplify the existing attestation types, which in turn will result in simplified interaction with the FAssets system
• Add two new attestation types: AddressValidity and EVMTransaction

If this proposal is accepted, the above changes will be executed, which are described in more detail in the Songbird State Connector protocol repository.

2. Link to Code Repository

These are the repository branches containing the code changes to be deployed:

• Multichain client
• EVM verifier
• Doge indexer
• Attestation client
• Songbird State Connector protocol reference

3. Proposed Implementation Date Range

Deployment of the new attestation provider code on the Songbird network is expected to start shortly after the voting finishes and be completed quickly.
